Embodiment Construction

[0016] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] The ram-type main transmission mechanism of the milling machine of the present invention transmits the power of the drive motor (spindle drive servo motor 1) to the machine tool spindle 17 through the transmission device, and the machine tool spindle 17 drives the tool to rotate to realize milling.

[0018] Described machine tool main shaft 17 is arranged on ram 16 front parts, machine tool main shaft gear 13 and machine tool main shaft 17 are coaxially fixed, and machine tool main shaft 17 is provided with the automatic purging device that constitutes main shaft assembly, automatic broaching device 18, hydraulic pressure unclamping device. Device 21 and disc spring tensioning device 19, the tensioning and loosening of the tool are controlled by PC, when automatic tool changing, the automatic purging device starts to work to clean the ta...

Abstract

The invention provides a ram type main transmission mechanism for a milling machine. The ram type main transmission mechanism comprises a spindle driving servo motor, a transmission gear box and a machine tool spindle, wherein the machine tool spindle is arranged in the front of a ram; the transmission gear box is arranged at a position, which corresponds to the machine tool spindle, of the ram; the lower part of the transmission gear box is positioned in the ram; the spindle driving servo motor is arranged on the ram; an input shaft of the transmission gear box is connected with the spindle driving servo motor through a coupling; an output shaft of the transmission gear box is connected with the machine tool spindle through an output gear and a machine tool spindle gear; and the input shaft and the output shaft of the transmission gear box can be connected with each other through multilevel gear transmission pairs which are arranged on different transmission shafts and can realize high-gear and low-gear rotational speed output. The transmission gear box and the ram are separated from each other, transmission of the transmission gear box is realized by gears, transmission rigidity is high, the size of the ram is small, the ram is simple in structure, the transmission gear box is convenient to mount and maintain, and the ram type main transmission mechanism is modularly designed and manufactured easily.

Description

(1) Technical field: [0001] The invention relates to a machine tool transmission system, in particular to a milling machine ram type main transmission mechanism. (2) Background technology: [0002] In order to adapt to different processing ranges and processing conditions, there are a variety of ram-type main transmission mechanisms for milling machines with the same layout and structure. For example, the main transmission mechanism and ram are designed as an integral gear transmission, and the main transmission mechanism and ram are designed as separate parts. Synchronous belt drive, etc. This type of mechanism has its characteristics and limitations: if the main transmission mechanism and ram are designed as an integral gear transmission, the ram structure is huge, the processing is complicated, the workmanship is poor, and the installation and maintenance efficiency is low; the design components of the main transmission mechanism and ram are One-piece synchronous belt tr...
